I know this from working Coal Worker's Pneumoconiosis [Black Lung] cases. Deposed dozens of doctors in 3 states who all reliably phrase their intake history in terms of how many 'pack years' workers reported smoking. ie, 3 PPD for 20 years = 60 PYs, 1 PPD for 30 years = 30 PYs.

But even then, common sense tells you that they are making this comparison knowing that cigarette smokes normally consume in terms of PPD, and joint smokers consume in terms of joints per week or month.
